> Issue Type: New Feature
> Components: Java

> Assignee: Ji Liu
> Priority: Critical
>
> Currently we already implemented {{RangeEqualsVisitor/VectorEqualsVisitor}} for comparing range/vector.
> And ARROW-6211 is created to make {{ValueVector}} work with generic visitor.
> We should also implement {{ApproxEqualsVisitor}} to compare floating point just like cpp does
